CLARINDA, IOWA, ASSIGNOR TO CLARINDA LAWN MOWER COMPANY, OF CLARIN'DA, IOWA.

GEARING DEVICE FOR POWER WASHING-MACHINES.

To all whom it may concern:

Be it known that I, ANnnEw J. DINKEL, a citizen of the United States, and resident of Clarinda, in the county of Page and State of Iowa, have invented a certain new and useful Gearing Device for Power ashing-Machines, of which the following is a specification.

The object of my invention is to provide a gearing device for power washing machines.

A further object is to rovide means of new and novel construction whereby continuous rotary motion of one shaft imparts alternating rotary motion to another shaft.

Still a further object is to provide a support with a hinged cover and a shaft rotatably mounted in the cover and a source of power adjacent to the 11 per portion of the support, with simple an direct gearing connections between the source of power on the support and the shaft in the hinged member.

Still a further object is to provide in such a machine means for connecting the power shaft mounted on the support in operative \relation with the shaft mounted on the member hinged to said support, and to provide means for connecting said hinged member whereby the hinged member may be raised or lowered without interfering with the gearing mechanism.

Still a further object is to provide such a gearing device including simple means for taking up play between the gearing membeing shown in section.

port adjacent to the bracket 14 is a supporting bracket 17,on which rests a motor 18 or other suitable source of power, having. the power shaft 19.

Mounted on the'shaft 16 is a gear casing, the parts of which are indicated by the reference characters 20 and 21. The gear casing members 20 and 21 have bearing members 22 formed thereon to receive the shaft 16. On the gear casing member 20 is a laterally extending sleeve 23, which receives and is secured to oneend of the bearing member 24.

The power shaft 19 extends through the sleeve 24 into the lower part of the gear casing member 20, and formed on the inner end of the shaft 19 is a worm gear 25 in mesh with a gear 26 on the shaft 16.

Screwed into the gear casing member 20 in line with the end of the shaft 19 on which the worm gear 25 is formed, is a plug 27 having a hollow inner end in which washers 28 are received. Between the washers 28 and the end of the shaft 19 is a ball 29. Should the gears 25' and 26 become loose or worn, it will be seen that they may be tightened by screwing the plug 27 in-' wardly, or by taking it out and adding more washers 28 and then screwing it into place until the parts are tight.

In this connection it may be noted that the entire motor and motor shaft may be turned pivotally on the shaft 16 until the motor is swung over the upper part of the support and does not project beyond the sides thereof.

Mounted on the upper part of the gear casing 21 and communicating therewith is an ordinary grease cup 30.

A gear casing member 31 has formed thereon a bearing 32 for a. shaft 33 arranged at right angles to the shaft 16 and extending over the hinged member 13. A coacting gear casing 34 is secured to the gear casing 31, and formed on the gear casing members 31 and 34 are bearing members 35 for the shaft 16.

On the shaft 16 is a worm gear 36 in mesh with the gear 37 on the shaft 33. The worm gear 36 is fixed and the worm gear 37 is loosely mounted. I

Slidably and rotatably mounted within the gear casing 31 is a clutch device comprising a collar 38 having pins 45 slidably projecting toward the worm gear 37 through a collar 39 fixed on the shaft 33 and adapted in one position of the sliding movement of the collar 38 to enter openings 40 in the side of the worm gear 37. Above the collar 38 is a grooved yoke 44 adjacent to the bearing member 32 secured to a rod 43 which receives a coil spring, 42 which yieldingly tends to hold the clutch member 38 in engagement with the worm gear 37. The clutch member 38 may be moved away from the worm gear 37 by means of the rod 43 slidably mounted in the gear casing member 31, having on its end Within the casing 31 the downwardly projecting yoke 44 with the groove over the clutch member 38, whereby the rod 43 is mounted to permit rotation of the clutch member 38 and to cause sliding movement of said clutch 38 when said rod 43 is moved longitudinally.

The outer end of the rod 43 is pivoted between the arms of the yoke 46 having a suitable handle 47; The arms of the yoke 46 have curved faces 48 adapted toengage the gear casing member 31 so that by tilting the part 47 the rod 43 may be made to draw the clutch 38 away from the worm gear 47 for throwing the shaft 16 out of gear with the shaft 33.

Mounted on the shaft 33 is a sleeve 49. The sleeve 49 and the shaft 33 project into the gear casing 50 on the central upper portion of the hinged member 13. The shaft projects beyond the wall of the gear casing and beyond the sleeve 49, and on the projecting end of the shaft 33 is a bevel gear 51. The casing 50 has a movable cover member 52 bolted upon it. Mounted on the cover member 52 and in the bottom wall of the casing 51, and supportedagainst downward movement by the member 53, is a hollow sleeve 54 which is mounted for rotation in the gear casing and receives in it slidably but non-rotatably an angular shaft 55 in the upper end of which is a head 56. ()n the lower end of the shaft 55 is an ordinary dolly 57.

Formed substantially midway of the sleeve 54 is an annular pro ecting member 58 having annular slots in its upper and lower surfaces to receive the'hubs of horizontal bevel gears 59 and 60 rotatably mounted on the sleeve 54. Projecting laterally from the member 58 is an arm 61 which forms a bearing for the rotatably mounted cylinder 62. On the cylinder 62 is a laterally extending pin 63 which travels in a horizontal elongated slot 64 in the Wall of the arm 61, as shown in Figs. 3, 4 and 6.

Formed in the surface of the cylinder 62 are notches 65 adapted to be engaged by a pin 66 slidably n'iounted in an opening in the wall of the arm 61. The pin 66 is yieldingly held toward the cylinder 62 by means of a spring 67, the outer end of which engages the screw plug 69 screwed into the outer end of the opening 68.

Formed on the upper surface of the cylinder 62 is a lug 70, and formed on the lower surface thereof is a similar lug 71 shown in full lines in Fig. 3 and in dotted lines in Fig. 4, said lugs being curved on the surfaces farthestaway from the center of the cylinder 62 and having flat edges or surfaces adjacent to the center of the cylinder 62. Said lugs 70 and 71 are arranged substantially at right angles to each other, as illustrated by the full and dotted lines in Fig. 4.

Projecting upwardly from the bevel gears 60 is a pin 72, and projecting downwardly from the bevel gear 59 is a similar pin 73. The parts described are so arranged that when the shaft 33 is given continuous rotary motion the bevel gears 59 and 60 will be rotated in opposite directions. One of the lugs 70 or 71, as for instance the lug 70, will stand out of the path of travel of the pin 73, while the lug 71 will be in the path of travel of the lug 72, so that the rotation of the gear 60 will cause the pin 72 to engage the lug 71 for carrying with the pin 72 the cylinder 62, the sleeve 54 and the shaft 55, thereby rotating the dolly in one direction.

When the dolly has traveled for a certain distance the pin 63 engages the stop 73 projecting inwardly from the wall of the casing 50 at one side thereof, whereby the cylinder 62 is rotated a sufficient distance so that the pin 73 on the bevel gear 59 will be engaged by the lug 70 as the bevel. gear 59 rotates, while the lug 71 will stand in position so that it will be cleared by the pin 72. The dolly shaft 55 will then be rotated in the opposite direction from that of its first rotation until the pin 63 engages the stop 74 on the interior of the casing 51 opposite the stop 73, whereby the pin 63 will be swung back to its original position and the direction of the rotation of the shaft 55 will be reversed.

1n completing the description of the mechanism, it may be said that the cover member 13 is mounted for hinged or pivotal 13, having bearings 76 receiving the shaft 16. It will be seen that the cover member 13 is thereby hinged in such a way that it swings on the center of the shaft 16 so that the gears 36 and 37 are in meshand are not interfered with by the upward swinging movement of the hinged member 13.

In the practical operation of my improved washing machine, power is supplied to the mechanism from the motor 18. The shaft 19 and the worm gear 25 transmit rotation to the gear 26 in the shaft 16, and thence through the gears 36 and 37 to the shaft The bevel gear 51 on the shaft 33 rotates the gears 59 and 60 in opposite directions, thereby imparting alternating rotary motion to the shaft 55 in the manner hereinbefore described. The yieldingly mounted pin 66 tends to hold the cylinder 62 in any of its adjusted positions with the point of sa1d pin 66inserted into one of the notches 65.

When desired thedolly shaft 55 may be disconnected from the power shaft 16 and the motor shaft by swinging the handle 47 downwardly, thereby causing the project ing ends of the yoke 46 to engage the member 32 and pull the clutch 38 out of engagement with the gear 37. By raising the handie 47 the spring d1 will be permitted to move the clutch 38 to engaging position. If it is desired the cover member 13 may be raised without being interfered with by the gears of the machine. be swung upwardly and over the body of the support when desired, so as to make the machine occupy a minimum of space.

I will now describe in a general way the means of connecting the shaft 16 with the wringer. Arranged at right angles and adjacent to the fixed cover member 12 is a fixed cover member 77, over which is mounted a wringer 78, having a projecting shaft member 79. The shaft 79 and the shaft 16 are operatively connected by suitable gearing devices within the gear casing 80. It

will be noted that the wringer is placed at right angles and adjacent to the shaft 16, so that when the hinged cover is raised it is swung back over the shaft l6, thereby allowing the operator free access to the washing machine tub from two sides. The advantage of such a general arrangement as is here set forth is obvious.
